Reprocessed uranium (RepU) Reprocessed uranium (RepU) is a product of nuclear fuel cycles involving nuclear reprocessing of spent fuel.

Uranium dioxide is the form in which uranium is most commonly used as a nuclear reactor fuel.

RepU recovered from light water reactor (LWR) spent fuel typically contains slightly more U 235 than natural uranium, and therefore could be used to fuel reactors that customarily use natural uranium as fuel, such as CANDU reactors.

Pu 239 is a viable fuel and must be accounted for even when a highly enriched uranium fuel is used.

Thorium uranium plutonium was investigated as a nuclear fuel for fast breeder reactors.

A boiling water reactor uses 235U, enriched as uranium dioxide, as its fuel.

research into the field of the fuel cycle (more especially the mining and processing of low grade uranium ore optimisation of fuel elements for power reactors).

MOX fuel) is dissolved in nitric acid, and the bulk of uranium and plutonium is removed using a PUREX type extraction (Plutonium URanium EXtraction) with tributyl phosphate in a hydrocarbon.

Carbides of uranium include uranium monocarbide (UC), uranium dicarbide (), and diuranium tricarbide ().

The most important oxidation states of uranium are uranium(IV) and uranium(VI), and their two corresponding oxides are, respectively, uranium dioxide () and uranium trioxide ().

Uranium Ore The key raw material for the project was uranium, which was used as fuel for the reactors, as feed that was transformed into plutonium, and, in its enriched form, in the atomic bomb itself.

One method of preparing uranium tetrachloride () is to directly combine chlorine with either uranium metal or uranium hydride.

Isotope separation Natural uranium consists of 99.3 uranium 238 and 0.7 uranium 235, but only the latter is fissile.

Breeding As opposed to current light water reactors which use uranium 235 (0.7 of all natural uranium), fast breeder reactors use uranium 238 (99.3 of all natural uranium).

Uranium nitrides obtained by direct exposure of the metal to nitrogen include uranium mononitride (UN), uranium dinitride (), and diuranium trinitride ().

Resende is of national importance and houses the Nuclear Fuel Factory complex of the Indústrias Nucleares of Brasil (Brazilian Nuclear Factories), the only one able to enrich uranium.

Supplying the fuel to the engine Fuel is transported from the fuel tank (via fuel lines) and pressurised using fuel pump(s).

In 1941 he began working with uranium hexafluoride, the only known gaseous compound of uranium, and was able to separate uranium 235.

The high uranium content makes carnotite an important uranium ore and also radioactive.

The NDRC Committee on Uranium became the S 1 Uranium Committee of the OSRD the word uranium was soon dropped for security reasons.

extractive metallurgy of uranium.

This was then heated to form uranium trioxide, which was reduced to highly pure uranium dioxide.

Highly enriched uranium (HEU) Highly enriched uranium (HEU) has a 20 or higher concentration of 235U.

Fuel stations in Uganda are running out of fuel.

Work was proceeding on three different techniques for isotope separation to separate uranium 235 from uranium 238.

Grades Slightly enriched uranium (SEU) Slightly enriched uranium (SEU) has a 235U concentration of 0.9 to 2 .

And then we get to uranium.

Actinium 227 occurs in uranium ore.

This creates a uranium concentrated precipitate.

Pitchblende, after removal of the radioactive elements uranium and thorium, was more radioactive than the uranium and thorium combined.

Water causes corrosion of fuel system components (pumps, fuel lines, etc.

The fuel injector ensures that the fuel is broken down into small droplets, and that the fuel is distributed evenly.

This can be performed directly in a direct carbon fuel cell, direct ethanol fuel cell or a microbial fuel cell.

In the case of a uranium bomb, this can be achieved by keeping the fuel in a number of separate pieces, each below the critical size either because they are too small or unfavorably shaped.

For example, ν 2.5 for uranium 235.

experimental fuel fabrication

Aggregate U 235 production About of uranium enriched to 89 uranium 235 was delivered to Los Alamos by July 1945.

Maintaining the correct fuel pressure is done by a fuel pressure regulator.

The reduction of by hydrogen produces uranium trichloride () while the higher chlorides of uranium are prepared by reaction with additional chlorine.

A flexible fuel vehicle (FFV) or dual fuel vehicle (colloquially called a flex fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.

The uranium was seized in a sting operation.

All uranium chlorides react with water and air.

Diesel fuel in general is any liquid fuel used in diesel engines, whose fuel ignition takes place, without spark, as a result of compression of the inlet air mixture and then injection of fuel.

The two ships had different fuel stores Bismarck was designed to carry 3,200 tons of fuel oil, but could store up to 6,400 tons of fuel in a normal configuration with extra fuel bunkers, the fuel carried could be increased up to 7,400 tons.

A relatively simple gun type fission weapon was made using uranium 235, an isotope that makes up only 0.7 percent of natural uranium.
